TRAP.

rea ers.

To all whom it may concern:

Be it known that I, EDWARD W. N. BOOSEY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Traps, and declare the followingto be a full, clear, and exact description of the same, such as willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to traps adaptable for use with bath tubs, washbasins, etc., of such form that the foreign matter may pass freelytherethrough, and of such con struction as to be readily secured to boththe inlet and outlet pipes irrespective of their relative position.

In traps formed of a single piece in which the positions of the inletand outlet are relatively fixed, it frequently happens that one or theother of the pipes to be connected therewith must be formed with a bendin order to make the proper connection with the trap, and as it isdesirable that these pipes shall have as few bends as is possible, theinvention shown comprises a trap in which the relative position of theinlet and outlet connections may be altered to agree with the positionsof the inlet and outlet pipes. The invention, therefore, consists incertain peculiarities of construction whereby these objects may beaccomplished as hereinafter more fully described and claimed and shownin the accompanying drawings in which- Figure 1 is a vertical section ofa trap embodying my invention.

Fig. 2 is a section on line a:w of Fig. 1.

Fig. 3 shows an alternative form of the structure.

Fig. 4 is a section on line y-y of Fig. 3.

Similar characters refer to similar parts throughout the drawings andspecification.

The trap is of that general type in which the seal chamber 1 is formedof a cylindrical shell having an inlet 2 at or near the bottom thereofand an outlet 3 at or near the top in which there are no internalprojecting parts against or about which foreign matter may lodge andclog the trap. The inlet 2 is provided with an upturned pipe-receivingSpecification of Letters Patent.

extension i, and the outlet 8 is provided with a like formed extension 5with which the inlet and outlet pipes connect respectively.

The seal chamber 1 is formed of two substantially like parts 6 and 7.The upper part 7, with which the extension 5 is integrally formed, isprovided with an annular, internally threaded, flange 8 of greaterdiameter than the body of said part providing a seat 9 for a softpacking 10, and the lower part 6 is provided with an annular, externallythreaded, ring 11 to engage the flange 8 of the upper part 7. Thepacking 10 is situated between this ring on the part 6 and the seat onthe part 7. The body 6 is provided with a portion 12 extending beyondsaid threaded ring portion 11 having the same internal diameter as thebody portion 6, and the external diameter of which is somewhat less thanthe internal diameter of the portion '2' within which it extends, thusforming an interstice 13 between the inner face of the wall of theupperpart 7 and the outer face of the extension 12.

This provision of an interstice, as stated, enables the soft packing10', when compressed by screwing the lower part 6 into the upper part 7,to be forced up into said interstice, whereby the point at which the twoparts become seated is not fixed, and allows the two parts to be turnedone relative to the other one or more complete turns after the packinghas been so compressed that no leakage may occur.

The packing 10 may be of any soft material adaptable for the purpose butis preferably formed of wicking and putty as is commonly used byplumbers in the packing of joints of this nature, and which may bereadily forced into the interstice in the manner stated.

An alternative form of the extension is shown at 12*, in Figs. 3 and l,in which form of the device the outer surface of the extension islongitudinally grooved, the ribs between the grooves quite closelyengaging the inner surface of the wall of the portion 7. The packing maybe forced into the grooves by screwing one part into the other whichwill cut or break the forced out part of the packing into smallparticles and these will readily wash out of the trap when flushed,whereas, in the form shown in Figs.

' tion 12, whereas if the 'in a plumbing system may be applied to Vvided with the inlet 2 1 and 2, a portion of the packing of ring likeshape might be forced beyond the end of the extension and possibly clogthe outlet. As shown in Fig. 1, the lower part of the trap is providedwith a clean-out opening closed by the plug 15, but in some cases,especially if the trap necessarily rests near or upon the floor, thisclosable opening may be correspondingly positioned in the part 7 or uponthe side of either of the two parts as may be found desirable.

It is to be noted'that the part 12 or 12 is formed on thatportion of thetrapproand the direction of flow of fluid through'the trap tends toforce all matter away from the end of the porfiow were in the reversedirection matter might lodge'against the end of this portion 12.

This. method of uniting two similar parts other port-ions of the systemthan the trap, for instance, a pipe line into which'other pipes lead,and if two joints of the pipeline be united in the manner shown, the

threaded openings therein for the connection of branch plpes may be soturned as to meet such pipes without the necessity of making bendstherein.

Having thus briefly described my invention, what I claim is- 1. Ajointbetween the two unitable parts each having a lateral extension for apipe connection therewith comprising an internally threaded portionforming a terminal of one of said parts greater in diameter than thebody of said part, an externally threaded portion on the other of saidparts for engagement with the first named part, the two parts beingformed to provide an annular channel: between the assembled parts, the

said last named part having a portion extendingbeyond the threaded partthe exterior surface of which iscorrugated and less in outsidediameterthan the internal diameterof-thepart into which it extendsproviding a space between the parts when assembled communicating withthe annular channel, and a compressible packing in the annular channel,the interstice providing a Copies of this patent may be obtained forfive cents each,

7 packing forced into the relief space for the packing to allow theparts to be relatively turned to accommodate the pipe connections afterthe joint has been therewith comprising, an extension on one of saidparts adapted to be positioned within the other part and spaced from thewall thereof, the outer surface of the extension being roughened orcorrugated, and a compressible packing between the parts adapted to beforced into the space whereby the lateral extensions may be relativelyposi tioned. by a rotation of the parts after the joint has'been madefluid tight.

A joint between two separable parts comprising a longitudinally groovedend on one of said parts extending into the other part, and acompressible packing between said parts adapted to be forced into saidgrooves.

A joint between two separable parts comprising an end upon one of theparts adapted to extend into the other part beyond the plane of thejoint and spaced from the wall thereof, the outer surface of theextension being creased or grooved, a packing space between the parts incommunication with the space between the said extension and surroundingwall, and a compressible packing in said packing space, the grooves orcreases serving to break up the space by a setting up of the joint.

5. A joint between twoseparable parts comprising a longitudinallygrooved end upon one of said parts extending into the other part, apacking space between said parts in communication with the grooves, anda compressible packing in said packing space.

In testimony whereof, I sign this specification in the presence of twowitnesses.
